Mitochondrial Dna Variability Among Six South-American Amerindian Villages From The Pano Linguistic Group, Celso T. Mendes-Junior, Aguinaldo L. Simoes

Human Biology Open Access Pre-Prints

Although scattered throughout a large geographic area, the members of the Pano linguistic group present strong ethnic, linguistic and cultural homogeneity, a feature that causes them to be considered as components of a same “Pano” tribe. Nevertheless, the genetic homogeneity between Pano villages has not been examined before. To study the genetic structure of the Pano linguistic group, four major Native American mitochondrial DNA (mtDNA) founder haplogroups were analyzed in 77 Amerindians from six villages of four Pano tribes (Katukina, Kaxináwa, Marúbo, and Yaminawa) located in the Brazilian Amazon. The central position of these tribes in the continent makes them …

Studies On The Synthesis Of Orthogonally Protected Azalanthionines, And Of Routes Towards B-Methyl Azalanthionines, By Ring-Opening Of N-Activated Aziridine-2-Crboxylates, Keith O'Brien, Keith Ó Proinsias, Fintan Kelleher

Articles

Orthogonally protected azalanthionines were successfully synthesised by the ring-opening of N-activated aziridine-2-carboxylates with protected diaminopropanoic acids (DAPs). The required DAPs were also prepared by ring-opening of N-activated aziridine-2-carboxylates with para-methoxybenzylamine, but it was found that the choice of aziridine protecting groups dictated both the success of the reaction as well as the regioselectivity of the isolated products. Attempts to extend the methodology to the preparation of the more sterically demanding b-methyl azalanthionines have, so far, been unsuccessful.

Illness Perceptions Of Polycystic Ovary Syndrome, Elizabeth Baker

USF Tampa Graduate Theses and Dissertations

Polycystic ovary syndrome (PCOS) is a chronic illness that affects approximately five million premenopausal women in the United States and is associated with significant cosmetic, reproductive, metabolic, and psychological consequences. Despite its prevalence, few studies have explored the lived experiences and illness perceptions of women living with PCOS. Identifying illness perceptions of women living with (WLW) PCOS is important, because mounting research suggests that a person's perceptions of their chronic illness and its management determine that person's coping behaviors (e.g., adherence, self-management) and, consequently, illness outcomes.

In this dissertation, the Common Sense Model (CSM) is used as a framework to …

Kosovo’S Verification Procedure For Diplomas Issued By Private Providers Of Higher Education, Mirushe Dalipi Latifaj

Theses

This capstone project addressed the issue of regulation of the verification procedures for diplomas and other documents issued by the Private Providers of Higher Education (PPHEs)[1] in Kosovo. This verification procedure has created a problematic situation. Firstly, in the legal aspect, it violates the applicable 2011 Law on Higher Education[2] which states the principles that “all institutions of higher education are equal before the Law”. “All students and personnel of the institutions of higher education should have equal opportunities without any discrimination”. Secondly, since the Kosovo Accreditation Agency (KAA) evaluates and accredits both public and private institutions of …

Calcium Homeostasis In Escherichia Coli: Characterization Of Mutants And Genome Expression Of Mg1655, Muhammad Arif, Josh Howard, Louis S. Tisa

Molecular, Cellular & Biomedical Sciences

While the role of calcium ions as secondary messengers has been well described in eukaryotic cells, little is known about calcium homeostasis in bacteria at the physiological and molecular levels. Genetic and genomic approaches were used to address calcium regulation and to identify genes (cal) involved in calcium homeostasis. Transposon mutagenesis of Escherichia coli generated several calcium-sensitive mutants that fell into three categories: (i) Ca2+-sensitive chemotaxis mutants, (ii) Ca2+-sensitive cell division mutants, and (iii) Ca2+-sensitive mutants that showed no defects in cell division or chemotaxis. The physiological properties of these Ca2+-sensitive mutants were determined. Besides calcium-sensitivity to 75 mM calcium, …

“You Are Turning Into A Hive Mind”: Storytelling, Ecological Thought, And The Problem Of Form In Generation A, Jenny Kerber

English and Film Studies Faculty Publications

This article discusses the relationship between literary form and contemporary ecological anxiety in Douglas Coupland’s novel Generation A. Coupland’s speculative fiction envisions a possible future in the wake of Colony Collapse Disorder, but the more generalized eco-anxiety the novel explores is applicable to a number of contemporary environmental issues ranging from climate change to ocean acidification. I argue that Coupland’s novel invites readers to consider the problem of representing ecological problems characterized by global scale, temporal uncertainty, and multiple origins. I then explore how Coupland responds to these challenges by stretching form in two directions. First, he juxtaposes and …

Developent Of A Phospholipid Encapsulation Process For Quantum Dots To Be Used In Biologic Applications, Logan Grimes

Master's Theses

The American Cancer Society predicts that 1,665,540 people will be diagnosed with cancer, and 585,720 people will die from cancer in 2014. One of the most common types of cancer in the United States is skin cancer. Melanoma alone is predicted to account for 10,000 of the cancer related deaths in 2014. As a highly mobile and aggressive form of cancer, melanoma is difficult to fight once it has metastasized through the body. Early detection in such varieties of cancer is critical in improving survival rates in afflicted patients. Present methods of detection rely on visual examination of suspicious regions …

A Combined Chemical And Biological Approach To Transforming And Mineralizing Pahs In Runoff Water, Chainarong Sakulthaew, Steve D. Comfort, Chanat Chokejaroenrat, Clifford Harris, Xu Li

School of Natural Resources: Faculty Publications

The water quality of lakes, rivers and streams associated with metropolitan areas is declining from increased inputs of urban runoff that contain polycyclic aromatic hydrocarbons (PAHs). Our objective was to transform and mineralize PAHs in runoff using a combined chemical and biological approach. Using ¹⁴C-labeled phenanthrene, ¹⁴C-benzo(a)pyrene and a mixture of 16 PAHs, we found that ozone transformed all PAHs in a H₂O matrix within minutes but complete mineralization to CO₂ took several weeks. When urban runoff water (7.6 mg C L−1) replaced H₂O as the background matrix, some delays in degradation rates …
